Missing functions in RESTful SDK

Hi Experts,

I started to have a closer look at the RESTful SDK and wanted to prepare a migration of a 3.1 project.

What I would like to know is, if there is a REST replacement for the following functions, as I was unable to find it in the documentation.

The product I'm working with is version 14.0.5.

• How to get information about the currently logged on user?
  • What is his/her eMail address
  • What is his/her full name
  • To wich group/groups does that user belong to
  • Favorites folder
  • Inbox folder
• Get something by name
  • How to query for a folder "xyz" (any hierarchy level)
• Authentication
  • Trusted
  • Active Directory

I really appreciate all hints in any direction.

Thanks in advance

Jan
